ZCU-14 3AXD50000005164 ABB External control unit

￭ External power supply for the control unit (XPOW)The control unit is powered from a 24 V DC, 2 A supply through terminal block XPOW.Using an external supply is recommended if• the control unit needs to be kept operational during input power breaks, for example, because of continuous fieldbus communication• immediate restart is needed after a power break (that is, no control unit power-up delay is allowed).￭ DI6 as a PTC sensor inputPTC sensors can be connected to this input for motor temperature measurement as follows.The sensor can alternatively be connected to FEN-xx encoder interface module. At the sensor end of the cable, leave the shields unconnected or ground them indirectly via a high-frequency capacitor with a few nanofarads, for example 3.3 nF / 630 V. The shield can also be grounded directly at both ends if they are in the same ground line with no significant voltage drop between the end points. See the firmware manual of the inverter unit for parameter settings.
